Crones

The isolated corners of our world harbor creatures older than humans, older than academies and mages, older even than elves and dwarves. The Crones of Crookback Bog are such creatures. No one knows their true names, nor what breed of monstrosity they in fact are.

Common folk have given these three sisters the names Weavess, Brewess, and Whispess, and call the threesome "Ladies of the Wood" or simply "The Good Ladies."
